WINDOW CONSTRUCTION.

Application led Februaryll, 1927.' Serial No. 167,903.

The present invention relates to window` constructions, and'more particularly to the 'type of windows having sashes that are mechanically operated or actuated.

Among the objects of invention, is to pro-` vide a novel window construction having a movable sash or sashes, such as that or those mounted in or on a window frame for swinging movement therein, and means for mechanically. operating the same, as also for bringing the sash or sashesinto closed and fully closed or stopped position, and also for holding the sash or sashes in moved position, 'whether in partly opened or fully l5 opened position, or partly closed or fully closed position, or both. The invention is applicable to windows having one or more movableV or swinging sashes, and which in the specific illustrated embodiment :is disclosed in connection with a three sash window of which the lower sash may be manl uall operated and the upper two sashes are mec anically y operated, the invention also comprehending the application of it. to win- '25 dows having but` out movable sash, or 'but 'one manually Operable sash and with any number, such as two, three or more mechanicallyjoperated sashes, or to any number of manually operable sashes with any number,

3o such as one, two o r more mechanically movable sashes, or to any number of sashes all mechanically operable, the particular embodiment herein disclosed being by way of illustration only and not by way of limitation. Y

Another object of the invention is vto provide novel means for mechanically operating the sashes such that they may work in unison orsimultaneously, and with means for nor- 40 mally limiting the movement of the operating'4 means orsashes, yet so` arranged and designed that the sash or sashes may-be disconnected from thev means for operating it or them whereby the sash or sashes may be readily reversed for cleaning the same or the like as desired. In the specific illustrative embodiment the actuating means comprises l a bar or rod slidably carried by the window frame and connected, asby means of a pin and slot device,vto the sash such that as the bar is slid, the sash may be caused to swing in or out as the case might be. As a stop means, a removable pin may be'so located vt9 limit the-movement 'of the bar and. Connected parts, but may be removeditopermit the lfurther movement ofthe connected parts, whereby the pin may be removed from the slot of the pin and slot connection between the sash and bar, to free the sash so that it can be reversed 4for cleaning and 60 other purposes. The bar may have a rack portion and is preferably operated or actuated by a manually operable means, such as a crank and gear device rotatably carried by the window frame, with the crank at a. point 65.

easily accessible to the person operating the Window.

Another feature of theinvention is to provide, when operating two or more sashes, means for relatively adjusting the sashes so that they will be even or in the same plane when closed, such adjusting means being effected by providing the crank and gear device With one of the gears loosely rotatable on the shaft of the crank and the other gear rotatably fixed to such shaft so as to posi-` tivelyvrotate therewith, such that one rack bar may be moved or slid to operate its respective sash to proper or adjustedv relation with respect to the other sash or sashes, Binding means, such .as a thrust screw may be then operated to fix the gears to operate in unison for. moving the bars simultaneously and hence the sashes connected theretgi?.

AA further feature'of the invention is t0 85 provide-means for holding. or locking the sash or sashes in` either moved or closed posit-ion. In the case of locking the sash or sashes in moved position, this may be effected by having a` member so associated with the bar or bars, as the teeth thereof,

such that it will normally be out of contact therewith but adapted, by the operating of an easily accessible crank means, to forcibly contact the member with the bar, so as to positively hold it in place and thus prevent movement thereof` andthe c'zonnectedsashes by reason of wind pressure or the like, until the member is released from the bar. The

member mentioned and the crank means may have cooperating cam means such that as` the crank is operated it may cam the member into or out of engagement with the bar or bars.`- 1

The invention also comprehends means for bringing the sash o r sashes to fully closed position and holdin or locking the Samel in such position, pre erably vafter the sash has been brought to substantially closed position by the mechanical operating means. This may be effected byv providing the sash or sashes with a memberhaving an inclined or cam portion, and a sliding bar having means, such as a member adjustably connected thereto, for engaging such inclined portion or cam, and thus cause a wedging or cammingaction so as to draw the sash tightly into fully closed or stopped position against the stops of the window frame. By the same means the sash or sashes are held land maintained in locked condition, until the barbe withdrawn and the member or members of the sash or sashes be released. This bar is preferably operated by a manually operable crank means rotatably carriedby the windowl frame and having the manual crank or arm thereof easily accessible to the operator of the window.

Referring now more in detail to the drawings, the invention is shown by way of an illustrative embodiment applied to a window frame having a lintel 1 connected to side `jambs 2 and 3, and a sill 4 carrying a ledge 5. The inner side of the frame may be covered with'a molding frame 6.

In the frame are shown a number of window sashes, of which the lower one is manually operated. It comprises side stiles 7, top rail 8 and the lower rail 9, and carries a pane 10. To the side stiles are connected plates 11 to each of which is pivoted at the upper end, a link or supporting arm 12, the

latter being pivoted at its lower end through a friction pivot means 13 connected to the side liamb of the window frame.l To each side jamb is also connected a. plate 14 having a channelled guide flange 15 in the chan# nel of which is adapted to slide a flange 16 of a shoe 17, the latter being pivotally connected by means of a pivot 18 to a projecting' end portion 19 -of the side plate 11. This construction may be duplicated on the opposite jamb. From this description it vwill be apparent that the sash may be man` ually operated by the sash turning about the pivot connection between the links 12 and l vtop rails 21 and bottoni rails 22, each sash also including a pane 23. To the side stilles 20 are pivotally connected at the uppercnds thereof, links 24, the lower ends ofl which are pivotally connected to plates 25 secured to the side jambs of the window, by any suitable means, such as screws. At the upper corners of the sash, such as at the opposite ends of the top rails 20, arc provided guide pins 26 extending into and adapted to slide in metal lined grooves or channels 27 formed in the side jambs 2 and 3 of the window frame. These metal lined pieces 27 may have flanges 28, secured, in

:any suitable manne; as by way of screws,

to the inner walls of the side jambs.

The top rail 21 of each sash may also have secured to it, in any suitable manner, a bracket or arm 29 extending inwardly and carrying at its inner end a runway pin 30 adapted' to slide in a slot 31 provided in a` runway member 32 of which the upper runi way member is secured to a bar 33, and the lower runway member is secured to a bar 34, both being sldable side by side in a channel groove or channel 35 provided in side jamb 2 of the window. The bar` 33 is longer than the bar 34 inasmuch as the former is designed to operate the upper sash, and the latter 4the lower sash of those mechanically operated. It will be also noted that the slot 31 in each of the runway members 1s open at one end so that the pin 32 is adapted, 1n a given relation, to move out of such slot for the purpose of permitting the reversal of between the links 24 and the stiles 20 thereof as also a swinging of the links about the lower pivotal connections thereof with the plates 25. At t-he same time the pins 26 in the upper rails will slide in the channels 27.

It will be seen from Figure 1, such movement, when the bars 33 and 34 are moved downwardly, will be effected from the dotted'line position of the sashes and connected parts to the full line positions thereof, which lat-ter positions are the open positions of the sashes. A reverse movement of the bars will bring the sashes to a close.

without danger of slipping.

l/Vhen the sashes are closed, they Contact on the inner sides thereof against stops 36 carried within the frame of the window, the inner edge of the ledge 5 also forming a part of the stop means for the lower Window sash.

For the purpose of mechanically causing a sliding movement of the bars 33 and 34 the lower end portions thereof may be pro vided with rack teeth 38 and 39 in mesh with teeth 40 and 41 of the gears 42 and 43 carried upon a shaft 44 forming a reduced diameter extension of a rotaryv member 45 rotatably carried in a bearing 4bracket 46 having feet 47 'secured by way of screws 48 or the like to the side jamb 2 of the-window frame. The shaft 44 is preferably provided with a fiat mill 49 for a part of the length thereof, and the opening in gear 43 is accordingly formed so that the gear 43 will lit onA said milled part, and the shaft 44 will be able to positively drive or rotate this gear The other gear 42, however, is loosely mounted upon the shaft 44, preferably on the unmilled part thereof. Normally, the gear 4 2 is made fasti so as to rotate' in, unison with thev gear 43 and the shaft 44, by means of a set screw `50 threaded into the end of shaft 444 and vhaving a washer or the like 51 engaging the gear43. The latter is then pressed against the gear 42 which in turn is forced against a shoulder portion 52 of the rotatable member 45. This will `effect va f rietional engage- 'ment among the parts sufficient to cause'the gear 42 to rotate with the gear 43 and` shaft 44 as` a unit. Thus it will be seen that'as the shaft 44 and gears 42 "and 43 are lro-`I tated, the bars 33 and 34 will lbe made to slide simultaneously or in unison, a'nd hence likewise cause an openingl of the `upper sashes.

If the sashes be not in proper relation, such as disposed in a plane, when closed, one sash may be readily adjusted relative to the other to bring them in the proper relation on the same plane when in closed position. This may be effected by loosening the screw 50 to remove the frictional engagement of the gears 43 and 42. 1 T heshaft 44 may be turned which will effect'a positive turning of gear 43 and sliding of bar 34. The gear 42, being relieved of frlctlonal'engagement sov with the gear 43, will now remain idle, Lthe shaft 44 rotating loosely therein. Hence the bar 33 -will 'also remain idle. When the desired adjustment has been made, the screwv 50 maybe again tightened and the gears locked together as before described, after which these gears will operate in unison.

The member 45 is provided with a socket 53 carrying a cross pin therein 54 yadapted l to be engaged by the slotted end 55 of a crank 56, the/inner end of the crank being capable of fitting loosely in the socket 53, and having at its outer end a handle 57 for manual'engagementI and operation of the crank. The block 46 may be provided with a recess or socket 58 adapted to receive a thimble 59, the inne-r end portion 60 of which is adapted to surround a partof the member 45 and extend through' an aperture 62 in the molding frame 6, such aperture being in registry with the socket 58, and the outer end of the member 59 bein closed except for HNI an aperture through whlchthe shank ofthe crank 56 passes. movable and replaced so thatthe slotted end of it may engage with the cross pin 54 and then may be rotated toturn the member 45 les and hence the gears 42 and 43 secured therei to. The rotating of these gears will cause a vsliding'of the racks of the' bars and likewise the bars themselves, so as to cause the sashes to open or close, depending upon the direction of rotation of the crank.

It will of course be understood that although two rack bars are` shown, that the groove 35 may be ofgreater width and adapted to permit the sliding therein of more than two rack bars, 'and in that case the shaft 44 may be of 'greater length so as to carry a greater number of gears so that they could respectively engage with their respective racks.4 On the other hand if it be vdesiredhin the illustrated embodiment, to disconnect one rack so that the sash operated by it may not be mechanically op'- erated, but only to operate the other mechanically, the gear driving that rack may' be removed from the shaft 54 and a spacer located in its place.

When the sashes are open, and for the purpose of preventing them from closing by reason of the force of the wind or otherwise, holding or locking means may be inf eluded to hold or lock the windows in moved position. Such holding or locking means may be effective not only to hold the sashes in open or partly opened condition, but also to hold them in closed or partly closed condition. Such a means, in the illustrated embodiment, comprises one or more sockets 63 which may be of any form, but in the form shown being rectangular in cross section, and forming a part ofthe block 46. Within the` socket 63 may be placed a locking membe in the form of a block 64 adapted to slide in the socket 63, and having an end'surface 65 thereof adapted to engage with the top of the teeth 38 and 39 of the bars 33 and 34. The-block member 64 may also be provided in one of its side faceswith a tapered recess -66 acting as a cam surface with which may cooperate the tapered end 67 of a screw 68 threaded into a threaded bore 69 in the block 46. The center line of the screw 68 is located off center of the socket 66, such that when the screw is operated. to move the tapered end 67 into the recess 66, it will act as a cam against the cam surface of the socket 65 and cause the block 64 to move inwardly and into engagement with the surface ofthe teeth, and forcibly bind the sam-e so as to hold the bars 33 and 34. against movement'. A reverse movement ofthe screw 68 will withdraw the tapered cam end 67 from the surface engaged by it in the socket 66 and permitthe block 64 to be relieved from the rack teeth of the bars 33 and 34, thus permitting a free movement of the rack bars. The screw 68 extends from the block 46 through a suitable aperture 70 provided in the frame' molding 6, and to the projecting end thereof is connected a manually operable handle 1 held secured in rigid connection with the screw by means of a set nut 72 threaded to the outer end of the screw. This handle 71 is located where it is easily accessible to the operator and preferably near the handle 57 which is also easily accessible to the operator. It will thus be seen from the above description that when it is desired to operate the sashes, the' handle 71 is operatedl to unlock the block member 64 from the rack teeth, and then the handle 57 operated to move the sashes to the desired positions, and when so moved, then the handle 71 operated in an opposite direction to turn the screw 68 andycause a. camming by way of elements 67 and 66 of the block 64 to forcibly engage thelatter with the teeth of the rack bars 33 and 34.

In order that the sashes may be swung to a given angl-e and no greater, a stop pin 72 may be engaged in the side j amb 2 in a position where it will be hit by the lower runway member 32, 'thus bringing the sashes at a stop at the desired angle or open posiare connected to the rack bars which are operated by a common means, the limiting of the movement of one of the runway members, will effect the stopping of-the whole system including the twobars. preferably extends through an aperture provided in' the frame-molding 2 and has a head 73 so that it may be readily engaged, when desired, to withdraw the pin. of withdrawing the p'in is to remove the stopping function, when it is desired to reverse the sashes. It will be apparent that when Vthe stop pin 72 is removed from the position shown .in Fig. l, and that when the bars are operated to a further movement than that limited by the stop pin, the runway members will arrive at a lower position, such that the pins 30 on the, sash brackets 29 will pass from and out of the open end of the slots and thus free the sashes whereby the operator may turn them completely around -or in reverse position whereby the opposite side of the sashmay be accessible When for cleaning or other "purposes The pin 72 The purpose bringing the sashes back into place the p ins will engage with the upper overhanging portion of the runways labove the slots 31 and a racking back of the bars'will effect a proper re-en agement of-.lthe pins in the slots so that 'tijde sashes inaythenoperate mechanically, and then the stop 'pin may be re-insertedin place.

When the sashes are brought to'closed position by the rack bars 33 and 34,. they may not close entirely tightly and for the purpose of bringing them tightly into closed poj sition or stopped condition against thel stops 36 of thewindow frame, the lower sash rails 22 may be provided on the oppo-l site side from where the brackets 29 are conneeted lto the sash, with laterally extending arms or bracket members 74 having a taf pered projection of linger 75 provided with an/ inclined or cam surface 76. When thewindow sashes are brought into substantially closed position, these brackets 74 will be brought into position such as that shown by "dotted lines in Fig. 5 of the, drawings. Ad-

jacent these and in the jamb 3 is provided a channel or slot 77 in which is adapted 'to slide a slide bar 78 carrying adjustable members 79 shown more in detail in Fig.4 12 of the drawings. These adjustable member 79 may be slid alongv the bar 78 to the desired point and heldin adjusted position by set screws 80. The members 79 preferably slide in metal channel pices-81 fixed into the groove 77.- Vhen the bar 78 and the tight engagement with the stop, 36 of thewindow frame, and incidentally will 'also hold the sashes locked in such position, such that the sashes cannot be opened even by the rack bar and gear mechanism on the side opposite of the window and when the locking means on that side should be released. In other words, the sashes may be locked doubly against unauthorized opening. When the bar 78 is operated in an opposite direction, the/ member-s 79 will be moved 4from they cam surfaces or edges 76 and thus releasethe bracket members 74 and hence the sashes, so that they may then be operated by the mechanical opening means. v l, The lower end of thebar 78 is provide with va slot 82 in which is adapted to operate a crank pin 83 carried by-a crank arm 84 securedto the end of a shaft 85 rotatably supported in abearing 8b fastened, as by way of screws, or the like, 87 to the inner face of the side jamb 3, as shown in Fig. 5. The ,Shaft 85 extends through an aperture in the frame molding 6 and has secured to the extending end thereof a handle 87 fixedto the end of the shaft by means ofa screw 88.

As the handle 87 is operated, the shaft 85 will l turn wit-h the crank 84 and the crank pin 83,A

the latter operating in the slot 82 and adapted to move the bar 78 from and to the full line position thereof tothe dotted lineposition thereof in Fig'. l2 of the drawings.
